Allanagrus montanus Manickavasagam & Palanivel , sp. n.

( Figs 8–14 )

Type material. Holotype female ( EDAU, registration No. Mym 22/2017), dissected and mounted on slide under five cover slips: INDIA, Namakkal , Kolli hills, 22.x.15, YPT, ginger & pineapple plantation, 11°24Ꞌ N 0 78°33Ꞌ E; K. Saravanan.

Paratype: 1 female on slide under four cover slips, same data as holotype.

Diagnosis. Females are distinguished as follows: from A. aurum , A. gladius , A. mayeri , and A. magniclava by the strong brown band on the fore wing (fore wing fairly uniformly hyaline in the other species); from A. orientalis as shown in Table 1.

Description. Female (holotype). Body length 750 µm. Body brown to yellow ( Fig. 8 ). Head light brown, eyes brownish red, ocelli red; scape and pedicel yellow, F1 to clava light brown to dark brown. Dorsum of mesosoma brown except pronotum and posterior of mesoscutum yellow, venter of mesosoma yellow; metasoma medially dark brown with anterior and posterior ends yellowish and white respectively; fore leg light brown except coxa yellow, meso- and metacoxae dark brown, femora and tibiae light brown, tarsi yellow, all trochanters yellow. Wings hyaline, fore wing with two brown-smoky bands, a lighter one behind submarginal vein and another a wider one just beyond stigmal vein ( Fig. 8 ).

Head width 223; mandible tridentate ( Fig. 9 ). Antenna ( Fig. 10 a, b) with scape 3.2× as long as wide, 1.7× as long as pedicel; fl1 0.6× as long as fl2; fl2 and fl3 subequal; fl4 0.8× as long as fl5, with one mps; fl6 1.1× as long as wide; clava 2.6× as long as wide, with 7 mps.

Mesosoma ( Fig. 13 ) 0.7× as long as metasoma. Fore wing ( Fig. 11 ) 6.8× as long as wide; longest marginal seta 0.9× wing width. Hind wing ( Fig. 12 ) 27× as long as wide; longest marginal seta 4.0× wing width.

Metasoma with ovipositor 2.66× metatibia length and exserted part 1.0× metasoma length ( Fig. 14 ).

Measurements (µm) of holotype. Head width 223. Antennal segment length/width: scape, 80/25; pedicel, 45/ 25; fl1, 43/10; fl2, 63/13; fl3, 65/15; fl4, 53/23; fl5, 63/28; fl6, 38/33; clava, 158/60. Mesosoma length 305. Fore wing length 775, width 113; longest marginal seta, 110; hind wing length 755, width 28; longest marginal seta, 113; metasoma length 428; ovipositor length 850, exserted part 388; metatibia, 320.
